142 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 96% — put it in D minor, a key signature of 1 flat. The tempo printed above is the median of the 142 readings; 67% of them land within 2% of it, and the middle eight tenths of them run from 103.7 to 114.1 BPM.

At 104.2 BPM one beat lasts 575.8 milliseconds, so a sixteenth note is 144 ms and a dotted eighth 431.9 ms — the delay times for this recording. Counted half as fast it is 52.1 BPM, counted twice as fast 208.4. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 451.7 Hz, which is 45.5 cents above concert A at 440 Hz — far enough that playing along at 440 Hz will sound wrong. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 6.79 dB: that is how far the level wanders from its own average, so a small number means a loud, flat master and a large one means a recording that still breathes. Its average loudness is 0.921 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
